The Beckwith Electric M-2168 Adapter Panel, used in conjunction with

the M-2001 series Tapchanger Control, uses modern electronic digital

design and digital processing circuitry to achieve an overall stability

and resolution unattainable with electromechanical and analog design

tapchanger controls. CMOS semiconductors are used throughout the

design. The M-2168 Adapter Panel, with the M-2001 series Tapchanger

Control, provides a solid state voltage control relay.

External connections are made to one terminal block located on the

rear of the adapter panel. M-2168: Replaces General Electric LRT-68

Controls.M-2148-P: Replaces General Electric LRT-68 Controls and

includes the M-0115A and M-0127A for paralleling.
